1、 AR7030 high dynamic range, low noise short wave receiver The standard AR7030 receiver has been awarded a five star rating by Radio Netherlands and Table-top Receiver of the Year award 1996/97 by the World Radio TV Handbook, it has also been awarded five stars by Passport to World Band Radio. truly

2、a remarkable receiver. The AR7030 stunned the world when first released due to exceptionally high performance, indeed the AR7030 still wins the analogue / DSP battle in respect of high dynamic range and low noise, a testimony to the successful project between internationally acclaimed UK designer Jo

3、hn Thorpe and AOR. Table-top receiver of the year - WRTH 1996/97 # AR7030 this plus the standard fitted TCXO makes the AR7030 ideal for ECSS applications. The self tuning variable bandwidth synchronous detector is a pleasure to use and hangs on to the weakest of signals, audio quality is superb. Whe

4、re good strong signal handling, high performance and transportability are of great importance, the AR7030 is the solution offering an IP3 greater than +30dBm (typical +35dBm reduced by 10dB with the preamp on). Intermodulation free dynamic range with the 2.2kHz filter is typically 105dB 100/200kHz s

5、pacing, 104dB 20/40kHz and still better than 90dB 5kHz. This fantastic strong signal handling is aided by the innovative configuration of a lateral DMOS FET QUAD first mixer running at 15V, relay switching in the front end (not diodes) and the use of shielded inductors throughout the signal path.

Selectivity too is razor sharp typically offering greater than 90dB 5kHz SSB, almost 100dB 10kHz and greater than 100dB 20kHz, these excellent figures are achieved by the implementation

Larry Magne - Monitoring Times & Radio Japan “.arguably the best receiver on the market, regardless of price.” “. Dynamic

20、 range is excellent at both 5 & 20 kHz separation.” “. overall audio distortion is good-to-excellent.” Passport to World Band Radio 1997 (nearly 5 pages of review!) Dynamic range is breathtaking at spacings of 5kHz and 20kHz, with respective third- order intercept points being +1dB and +30dB. Indeed

21、, it is so outstanding that our laboratory manager had to visit with Hewlett-Packards signal generator maven and upgrade certain of our testing gear in order for us to be able to accurately measure performance of this calibre. .What these measurements showed is that the 7030s dynamic range and third

22、-order intercept points are at levels normally associated only with the finest in professional hardware. Yet, the 7030 does this at a fraction of the price. Awarded five stars and Editors choice.

23、cation puts that of almost everything else on the market to shame. If our sample is typical - and there is no reason to suppose it was not - some aspects of its performance almost certainly exceed the ability of the average test laboratory to measure and establish them.

24、s utterly right. .sheer performance allied to extreme versatility and excellent build quality, the AOR 7030 PLUS remains one of the worlds most desirable receivers. A word of praise is also in order for the truly excellent manual. Awarded five stars and table-top receiver of the year 1996/97. RadCom

25、 (RSGB) - The Peter Hart Review “The strong signal performance is extremely good. The intermodulation measurements are at the limit of my measurement capability and the close-in result by far the best I have measured on any general coverage receiver. .The excellent RF performance of the AR7030 is certainly most apparent in on-air tests. Jonathan Marks - Radio Netherlands “Of the synthesizer. this is an extremely low sideband noise design.” “We think that the phase noise of the AR7030 DDS is excellent, and much better than comparable priced and even much higher priced receivers.”
